WORD-COUNTING ATTACHMENT FOR TYPE-WRITING MACHINES.

Specification of Letters Patent.

Patented May '7, 1918.

Application filed October 25, 1916. Serial No. 127,724.

and State of California, have invented certain new and useful Improvements in Word.- Counting Attachments for Type-Writing Machines, of which the following is a specification.

This invention relates to a word countin attachment for typewriting machines an particularly to an attachment of thls kind which is especially adapted for counting the words and characters of telegrams and similar messages Written on ty ewriters.

The principal object of t e present invention is to provide a device which is readily attachable to a typewriting machine and which will automatically count and register on a suitable device the number of words and characters counting as words which have been written by the machine to which the device is attached.

Another object is to provide a device which will positively register every word and character counting as a Word whether in the upper or lower case of the typewriter.

keyboard.

Another object is to provide a counting mechanism which will count the words in. groups of 50 each, the letter type of night messages being at present charged for on the basis of a minimum rate of 50 words or less.

Another object of the invention is to pro-, vide a counting and registering mechanism which requires but a small amount of power to operate it, in order that the additional eifort will be hardly noticeable to the operator of the machine to which the mechanism is attached. I

The above and other objects and the novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings, in which similar reference characters indicate the same parts in the several figures of the drawings. a

Figs. 9 to 14, inclusive, are perspective views of elements of the registermg mechanism, and

Fig. 15 is a sectional view of the mounting of the registering wheels, taken on the line XV-XV of Fig. 4.

Referring to Figs. 1 to 6 in particular, 20 and 21 are base bars having holes extending therethrough to receive screws 22 which rigidly connect the attachment to the bottom of the typewriting machine M. Adjustable bearing blocks 23 are mounted in the bars 20 and 21 and support a fulcrum rod 24 at its ends, the rod 24 being held in place by the set screws 25 and adjustable by the screws 26 which adjust the blocks 23' vertically in the blocks 20 and 21.

Two frames, W and C, are rockably mounted on the fulcrum rod 24, the frame W being rockable by the key levers of alphabet characters and the frame 0 being rockable by thev levers of other keyboard characters which count as words. The attachment shown is particularly designed to count the words and characters of telegrams, especially lengthy day or night letters. In such messages all the characters, punctuation marks, etc., count as words and this mechanism is designed to register them, so that they will be included in the total number of words, etc., to be charged for.

The frame W consists of two side bars 271 and 272 connected together at their ends by the front and rear bars 273 and 274 respectively. The rear bar 274 is depressible by the lever which causes the printing of the first letter of each word, and a friction spring 275 mounted on the rod 24 engages mechanism when the first letter thereof is struck. Movement of the frame W along,

the rod 24 is prevented by collars 28 secured to the rod 24 by set screws. 7

.The frame C consists of two side bars 291 and 292 which have one end pivoted on the rod 24 and at their rear ends they are connected by a back bar 293. The back bar 293 iscapable 'of being engaged by'any one of the levers of the keyboard characters other.

- than the alphabet key levers, and when thus.

coiled around the fulcrum rod actuated, the mechanism connected to the frame C will register the written character as a word. The upper edges of both the back bars 274 and 293 are notaled as indicated in- Figs. 2 and 3, so that the frames Wand C will only be rocked by the levers intended to operate them. A spring 294 has one end 24 and secured to the adjustable ratchet collar 295 by means of which the tension of the spring may be changed. The other free end of this spring extends outwardly at right angles to the rod 24 and beneath a crossbar 296 on the frame C, exerting an upward pressure to restore the frame C to its normal position immediately after each depression of said frame. r

The back bar 274 of the frame W is connected to the outer end of a crank arm 30. and the inner end of the arm 30 is secured to a U-shaped rocker plate 31. The plate 31 has a part 311 which extends beneath the base bar 21, and the parallel parts 312 are pivotally supported on the fulcrum rod 24-at opposite sides of the base bar 21. The outer side of the rocker plate 31 has an upwardly extending bar 32 adjustably secured thereto by screws 321. A dog 33 is pivoted at the upper end of the bar 32 and has a lateral extension 331 adapted to engage one of the fifty pins 34 on a wheel A which constitutes part of the registering mechanism to be described. A spring 332 on the bar 32 holds the dog 33 in such a position that when the back bar 274 of the frame W is struck anddepressed by an alphabet key lever, and the bar 32 is rocked, the extension 331 will engage a pin 34 and rotate the wheel A onefiftieth of a turn.

The back bar 293 of the frame C is connected to the outer end of a crank arm 35 and the inner end of the arm carries a U- shaped rocker plate 36 which has its sides 361 pivoted on a rod 37 extending through the base bar 21. The outer side of the rocker plate 36 has a bar 38 secured to it and a billshaped dog 39 is pivoted at the upper end of the bar 38. A spring 391 is connected to the dog and secured to the bar 38 and holds the dog in such a position that when the bar 38 is rocked by the depression of the frame C the bill engages a pin 34 and rotates the wheel A one-fiftieth of a turn. When the frame and bar are retracted the spring 391 permits the billto ride up over the next pin below it and move back out of'the path of the pins.

A bracket 40 is rigidly secured to the base bar 21 and extends upwardly and outwardly therefrom. A guiding element 41 is secured to the bracket'and is provided with notches 411 to receive and guidethex'bars 32 and 38. The registering mechanism is also mounted on the bracket 40.

The registering mechanism comprises a circular casing 42 in which are mounted the two independently rotatable. registering wheels A and B. The casing 42 has a stem 421 secured to its lower side, the stem being the parts thereon may be adjusted at the exact height desired. The side of the casing facing the machine is open to permit the removal of the parts therefrom, but the side away from the machine is closed. The casing also has two sight openings 423 and 424 in its'periphery and at the -front side to ex,- pose portions of the wheels A and B within.

A partition 43 is located inside the casing 42. and has a notch 431 which fits :1. lug 425 on the casing to properly assemble, and lock these parts together against rotation, but permit the removal of the partition and parts thereon. 'The partition has two hubs or bosses 432 and 433 on opposite sides of its center and also a bore through both bosses to receive a stem or shaft 44 integral with the spider arms 441 which carry the rim 442 ;of the wheel A. A nut 443 engages the threaded outer. end of the stem 44 to hold it in place. The partition is also secured to the casing 42 by a nut 434 which engages a threaded part of the hub 433. The two wheels A and B are thus coaxially mounted on opposite sides of the partition in the casing.

The rim of wheel A has fifty parallel pins extending from one face thereof and. the peripheral side of the rinr has a series of numbers 0' to 49 thereon, visible in succession through the window 423. It requires fifty successive steps of the wheel A to turn it a complete revolution. By mechanism to be described each eomplete revolution of wheel A causes wheel B to move up one step and show an additional 50 at the window 424, since the periphery ofthewheel B is provided with a series of numbers beginning with 0 and rising in steps of 50 to 2450. The opera tion of bars 32 and 38 moves the wheel A one step at a time-which is equal to the registering of one word or character at a time.

In order to prevent the mechanism registering more than one word at a time, a double-nosed compound pawl is employed, the pawl consisting of two members 45 and 46. The member 45 is pivoted at 461 on the member 46 and has two points 451 and 452 which alternately engage the pins 43 when the registering wheel A is rotated. The point 451 prevents the return of the Wheel and the point 452 prevents more than one pin passing a given point at each stroke of the actuating members 32 and 38. The member 46 of the compound pawl is pivoted on a pintle 471 mounted on a bracket 47 carried on the upper outer side of the casing 42, and has a forwardly extending tail provided with an integral lateral extension 462 which projects beneath the finger lever 48 also pivoted on the pintle 471. When the finger lever is'manually depressed the pawl member 46 will be turned which in turn -causes the member 45 to be lifted bodily to raise its points 451, 452 out of the path of the pins 34. The member 45 has a slot 453 through which the pintle 471 passes, and. the head of the pintle holds this member in place but allows the rear end of it to move freely. The finger lever 48 has an integral pawl finger 481 the outer free end of which extends through a hole 426 in the casing 42 and is adapted to successively engage the holes 49 in the rim of the wheel B to hold that wheel in the position in which it is moved by every complete revolution of the wheel A. A spring wire extends around a button 427 on. the casing and below the pintle 471, and the free ends 50 and 501 thereof bear upon the upper edges of the pawls 45 and- 481 to .yieldingly hold those members in engagement with the wheels A and B.

The pawls, brackets and part of the finger lever are inclosed by a small cap or casing 51 which has a bifurcated part 511 at the rear end engaging a headed button 512 on the casing 42. A cross bar 513 at the front end engages under a resilient latch 514 which consists of an integral part of the bracket extending forwardly and folded on itself to form a catch under which the edge 513 may be passed. The end of the finger lever 48 pro ects through the opening 515 in the casing 51 and by depressingthis lever I the pawls 45 and 481 will be raised and release the wheels A and B so that the latter may restore to their zero positions.

As the register wheel A is rotated by the actuating bars 32 and 38, it stores energy in a spiral retracting spring wire 52 which is set in a cup-shaped cam 53 which turns freely on the hub 432, see Fig. 15. The ends of the spring 52 are respectively secured to the cam 53 and to one of the spokes 441 of the wheel A. When the wheel A is turned, restoring energy will be stored in the spring, the cam 53 being provided with a projection forming a tooth 531 which is engaged by the end of the arm 541 of a double-armed cam tripping lever 54- pivoted at 542 on the partition 43. 'When the total number of words and characters registered by the wheel A is less than fifty, as for instance in a case where the total number of words and characters registered is twentyeight, the spring 52 will have enough energy stored therein to return the wheel A to its zero position when the finger lever 48 is depressed to release the wheel A.

A second spiral restoring spring 55 surrounds the hub 433 and has one end 551 secured to the hub and the other end 552 hooked around a spoke of the wheel B. Energy is.stored in the spring 55 as the wheel B is rotated by the Wheel A, and this spring will return the wheel B to its zero position when the finger lever 48 is depressed. The depression of the lever 48 permits both restoring spring 52 and 55 to operate and simultaneously return the wheels A and B to their zero positions. The stop 56 on the wheel B (see Fig. 5) engages the stop 57 on the partition to limit the return movement of the wheel B.

Each time the wheel A makes a complete revolution its restoring spring 52 is released by the movement of the trip arm 541 out of engagement with the cam tooth 531, see Fig. 4. The cam 53, when released, is rotated one complete revolution by the spring 52 and in the meantime the end of the trip arm 541 is returned by the spring 58 to a position to engage the cam tooth 531 and lock the cam against turning so that energy may again be stored in the spring 52;

The arm 541 is one part of a double-armed member 54 having a pivot opening 543, see Figs. 4, 5 and 12. The other part of the member 54 has two arms 544 and 545, the

former being approximately parallel to the arm 541 and carrying the rockable member 59. A pivot pin 595 passes through the holes 546 and 591 in the arm 544 and member 59, respectively. A trip finger or catch 60, see Figs. 4 and 13, slides along one face of the arm 545 and the shank of a stud 601 passes through the holes 592 and 602 of the rocking member 59 and finger 60, to pivotally connect them together. The connecting pin 601 passes through a slot 547 in the arm 545 and another stud 548 is secured in the hole 549 in the outer end of the arm 545 and passes through a slot 603 in the trip finger 60. This connection of the trip finger 60 to the arm 545 permits the finger to freely slide back and forth along the arm. The heads of the studs 601 and 548 hold the finger in place. A hook 604 on the outer end of the finger 60 is engaged by -a. tripping pin 61 on the inner side of the flange 442 of the wheel A, and this pin raises the trip finger 60, and rocks the double-armed member 54, throwing the arm 541 out of engagement with the ,face 531 of the cam tooth 532, allowing the cam tooth 532 tc rotate and release the stored 'energ During the rotation o the camtooth 532, its face 531 strikes and momentarily engages a projection 593 on the upper end of the rocker 59 and rocks the latter. This striking action of the face 531 against the projection 593 pulls the trip finger 60 inwardly toward the pivot 542 a sufiicient distance to draw the hook 604 of the finger out of the way of the 61 moves past the trip finger 60 just as the .fiftieth word is counted and then the finger 60 is immediately returned to its normal position by the spring 58. This spring is coiled around the pivot 542 and has one end hookedaround the edge of the opening 433 in the partition, as at 581, and the other end is hooked over the hook 594 on the rocker 59, exerting a yielding turning force on the rocker tending to push the trip finger 60 outwardly so that the hook of the finger will normally be in the path of the tripplng pin '61 on the wheel A.

The momentary arresting of the rotation of the cam tooth 532 by its face 531 striking the projection 593 at the upper end of the rocker 59, as above ex lained, is also for the purpose to allow an give suflicient time to permit the upper end of the arm 541 to return to its normal position, as shown in Fig. 4, and be again engaged b the face 531 of the tooth cam 532, the acce eratlon of which has thus been checked before said cam tooth 53 2 and its face 531 rotates back to its normal position, shown in Fig. 4, after e cam tooth 532 has been released from engagement with the upper end of the arm 541.

Just as the fiftieth word or character is registered by the wheel A, the tripping pin 61 thereon engages the arm 63 of a doublearmed actuating or advancing device which straddles a bracket 435 which is a part of the partition 43 and projects into the opening therein. The actuating device is pivoted on the pin 631 on said bracket, see Figs. 4, 5 and 9, and consists of a single piece of sheet metal doubled to provide two parallel arms 63 and 64, one arm 63 being located on the same side of the partition with the'wheel A and the other arm 64 being located on the side of the partition with the .wheel B. The lower end of the arm 64 has an advancing pawl 65 pivoted thereon, which pawl is engaged below its pivot 651 by the lower end of a spring wire 66 which tends to throw the pawl into line with the arm 64 and also so that the upperend of the pawl will engage the stop 642 on the in the spring 52.

pin 61 on the wheel A. The pin.

arm 64. In that position'the lower end 652- of the pawl 65 drops into engagement with the inner end of one of the holes 49 in the wheel B and a still further movement of the actuating device moves the wheel B forward one step which is equivalent toa complete revolution of the wheel A and the next higher multiple of fifty will be exposed at the window 424 of the casing 42.

The arm 63 is' adjusted so that the point 632 thereof will pass over the trippin pin 61 when the wheel A completes its fi ieth step. The free end of a spring 67 presses against the arm 63. One end of the spring 67 is hooked in a notch 633 in one edge of the arm 63 and the other end is coiled around the hub 433 and fastened thereto as at 671, see Figs. 4, 5 and 15. The spring 67 serves to return the advancer or actuator to its normal position, shown in Fig. 5, pushing the lower end of the pawl 65 against a stop 68 which lifts the polnt of the pawl out of the way of the wheelB, so that if the latter should be released the pawl would not prevent the restoration of the wheel'B to its zero position. The stop 68, see Figs. 5 and 11., consists of a bar having a slot 681 at one end to receive a pin 682 whereby the stop is secured in any desired adjusted position. The forward end of the bar is bent as at 683 so as to form the equivalent of a pin in the path of the pawl 65.

A limiting device 69 is pivoted at 691 on the partition.43 and is free to swing on its pivot so that normally'theLend of the arm 692 at the lower end of the device lies against the projection 642 on the arm 64 of the advancing member. When the advancer is swung forward to the leftin Fig. 5 the tooth 693 on the limiting device is swung into one of the holes 49 on the wheel B just at the moment that the advancer reaches the end of its stroke. This serves to prevent an overthrow of the wheel B and keeps it from moving forward more than one step at a time. The pin 57 on the partition 43, also serves as a stop' for the limiting device 69. The member 69 is so hung that gravity will immediately restoreit to its normal posltion,

as in Fig. 5, when the advancer is returned to its normal position by the spring 67.

As heretofore explained, each step which of the finger lever 48 also permits the spring 52 to restore the wheel A to its zero position,

so that both wheels will be ready for counting the words of another message. The total number of words and characters in the mes- 1,aes,174

registered by the two wheels.

While I have shown and described my invention as applied to counting wprds ofa telegram printed by a typewriter, sald counter mechanism, as will be easily understood from its construction and operation, may be employed and isreadily adapted for other and varied purposes and in conjunction with other mechanisms, as, for example, recording mileage traveled? by automobiles and other vehicles, number of messa es sent over a telephone, sales made by an in ividual salesman or total number *of sales in a department store, recording repeated operations of special machines used in manufacturing of pieces during a given period ozl.
